(HealthDay News) — Abdominal obesity is associated with increased risk for hip fracture, according to a study published in the Journal of Internal Medicine.
Anne Johanne Søgaard, PhD, from the Norwegian Institute of Public Health in Oslo, and colleagues examined the correlations of waist circumference, hip circumference, waist-hip ratio and BMI with incident hip fracture. Data were collected for 19,918 women and 23,061 men, aged 60 to 79 years, who were followed for a median of 8.1 years.
From electronic health registers, the researchers identified 1,498 hip fractures in women and 889 in men. There was a decrease in the risk for hip fracture with increasing BMI, plateauing in obese men. After adjustment for BMI and other potential confounders, there was a correlation for higher waist circumference and higher waist-hip ratio with increased risk for hip fracture.
Compared with women in the lowest tertile of waist circumference, those in the highest tertile had an 86% increased risk for hip fracture; in men, the corresponding increased risk was 100%. Particularly in men, the risk for hip fracture was increased considerably with lower BMI combined with abdominal obesity.
“In view of the increasing prevalence of obesity and the number of older people suffering osteoporotic fractures in Western societies, our findings have important clinical and public health implications,” the researchers wrote.
